Title: Strip-form superconductors
IPC: H01F6/06
Filed: 1966-12-12
Abstract: <PICT:1103140/C6-C7/1> <PICT:1103140/C6-C7/2> Superconductor strip comprising a binary intermetallic compound such as Nb3 Sn is produced by assembling at least three strips of the higher melting point element with the lower melting point element therebetween and at least one face of each adjacent pair being recessed whereby the lower melting point element is retained in place by capillary action during heat-treatment to form the compound.  The compounds may consist of oneof Nb, Ta, V in combination with Al, Ga or Sn.  Fig. 1 shows 10m thick strips 9, 10 and 6 of Nb with interleaved strips 7, 8 of Sn being fed through a cooled stopper 12 into a tubular continuous furnace 15 fed with an argon atmosphere. The Nb strip 6 has been previously rolled by a coarse grinding roller to provide recesses on both faces up to 7.5m  deep.  In the furnace, a slotted rod 18 of aluminium oxide acts as a guide for the strips which are also weighed down lightly by aluminium oxide bars.  The strips are pulled through by roller 20 and after passing over pulley 26 for tension control are subjected to a second similar heat-treatment in furnace 23; the finished strip is wound on roller 25. Heat-treatment is at 1000 DEG C. for 15-30 minutes and the finished product is shown in Fig.4 where superconducting layers 56, 57, 58, 59 of Nb3Sn each about 2m  thick are formed between Nb layers 51, 53, 52 and Sn layers 54, 55; the size of the tin strip is predetermined to ensure that it is just sufficient to fill the interstices in the niobium layer.  The tin may alternatively be provided as a coating, electrolytically deposited or evaporated on to the niobium before or after the recessing treatment.

Abstract: 1409300 Shovelling machines ATLAS COPCO AB 7 Dec 1972 [16 Dec 1971] 56557/ 72 Heading E1F  The shovelling means of a shovelling machine comprises a bucket 2 pivotally Mounted about axis 32 on a vertically swingable yoke 4 and a scoop 3 having arms 6 pivoted at 11 to arms 8 on the bucket 2 and being dimensioned so that it can nest within the bucket so as to be filled before the bucket when the machine is driven towards material to be loaded by the machine. The bucket is then raised until the scoop raised by the bucket becomes hooked onto the chassis of the machine by a latch 13 engaging a bar 12 between the arms 6. With the scoop so held the bucket is lowered and filled by again advancing the machine. The filled bucket is then raised and the machine moved to where the material in the scoop and bucket is to be discharge. The raising of the filled bucket raises the filled scoop clear of the latch B so that the bucket and scoop are simultaneously pivoted to discharge an appropriate actuation of the rams 26 extending between the bucket and the yoke. The scoop moves back into the bucket as they are emptied and the rams 26 are not contracted until the yoke has descended to a position where the bar 12 of the scoop will be below the latch 13.

Abstract: 1368070 Stereophonic systems; loud-speaker systems; acoustic devices A V BORISENKO 13 Dec 1971 57807/71 Headings H4J H4R and H4X A stereophonic sound-reproducing system comprises two loud-speaker assemblies each including a middle frequency loud-speaker unit having an acoustic lens which is arranged at an angle to a base line on which the two loudspeaker assemblies lie. The arrangement is said to make the spatial sound panorama practically independent of a listener's position on a line parallel to said base line. The system comprises two loud-speaker assemblies 1, each of which includes a low frequency and a high frequency speaker unit (not shown) positioned on either side of a central middle frequency unit including loud-speakers 2 and an acoustic lens 3 which is laminar in form and comprises between 6 and 8 plates 4 arranged at 40 degrees to the base line B. The design of the lens to give the "directivity patterns" required to give the required spatial effect is said to depend on the separation of the speaker assemblies. For lenses arranged at 40 degrees to the base line, the speaker assembly separation is quoted as 2À4 metres. The high frequency speaker units may be orientated at the same angle as the middle frequency units to the base line.

The primary windings of the coupling transformers are interconnected at points X, Y, Z as shown and are energized from a square wave pulse source S through a supply transformer T1. Each centre-tapped secondary winding is connected with two rectifiers 11-14, 21-24 to provide a full-wave rectified output V/2, these voltages being additive in series-connected resistors 15, 16 and 25, 26. The voltage drops across the resistors 15, 16 in circuit 10 is modified to (V/2 + U), (V/2 - U) by a voltage U between terminals A, B, and this condition is reflected by a similar voltage appearing across terminals CD which is either equal or amplified depending on the turns ratio of the coupling transformers T5, T6. Each resistor is shunted by a filter capacitor 17, 18, 257, 28. A further supply transformer T2 may be provided which is connected to the circuit supplying the input voltage. Initial balance is obtained by short-circuiting terminals A, B and adjusting potentiometer 19.

The antibiotic is an acid compound forming base-salts, e.g. with sodium or ammonium, having a proposed molecular formula C 47 H 78 O 13 , an ultra-violet absorption peak at 234À5 mÁ (# = 14,200), and having α,#-unsaturated ketone and polycyclic polyether structures in the molecule. It decolorizes KMnO 4  solution, gives a positive Dragendorff test and a negative FeCl 3  reaction, and is soluble in most organic solvents but insoluble in water. The sodium salt is a white crystalline substance melting at 227‹ to 231‹ C., having a proposed molecular formula C 47 H 77 O 13 Na. The antibiotic is isolated either from the whole culture broth or from the separated broth and mycelium, by extraction with an appropriate organic solvent. The whole broth is acidified, filtered after addition of a diatomaceous earth absorbent, and the filtrate is extracted with a water-immiscible solvent, e.g. ethyl acetate, while the filter cake is extracted with a water-miscible or -immiscible solvent, e.g. acetone or ethyl acetate. The extracts are combined, concentrated, and either treated with water to precipitate the crude antibiotic or subjected to purification on a silicic acid column, the product being finally recrystallized from ether to give the pure antibiotic. The antibiotic A-130-A has anti-bacterial and anthelmintic properties and may be used to treat or prevent avian coccidiosis in poultry, optionally after admixture with a poultry feed or pharmaceutical carrier.

Abstract: 1,256,027. Hardening development of photographic gelatine-silver halide materials. FILMFABRIK WOLFEN VEB. Dec.11, 1969, No. 60499/69. Heading G2C. Hardening development of an exposed photographic gelatine-silver halide material is effected in the presence of a dialdehyde or dialdehyde bisulphite compound with a developer containing as a clarifier a 1, 2-triazoloanthraquinone of the formula: - The dialdehyde preferably has the formula: wherein A is (CH 2  ) n , CH(CH 3 ), S, O, NH, Se or N(R) wherein R is CH 3 , C 2 H 5  or C 3 H 7  and n is O, 1 or 2. The dialdehyde may be in the form of its bisulphite. The 1, 2-triazoloanthraquinone is preferably used in an amount of 1 to 40 mg. per litre of developer. The developer may contain hydroquinone, N-methyl-p-aminophenol or 1- phenyl-pyrazolldone (3) as developing agent. Only 20 to 40% of the amount of known clarifiers need be used of the 1, 2-triazoloanthraquinones above. In addition these compounds have only a very slight effect on the stability of the developer, they do not colour photographic layers after development and display good solubility in the developer and hence do not cause turbidity when the developer is allowed to stand for a long time.
